Shimano Torque Wrench System - Adjustable 3-15NM for Bicycle Repair & Maintenance | Professional Bike Tool for Precise Bolt Tightening | Perfect for Road Bikes, Mountain Bikes & Cycling Enthusiasts

I got this torque wrench on the advice of my bike shop when I bought my new carbon bike.The good: it does what it says on the tin. When you achieve the desired torque, you will feel the handle "click" or suddenly give way. When it does, STOP. It does not ratchet after reaching your desired torque, so that click is the only warning you get. Fortunately, it's pretty hard to miss it. Just turn slowly, and pay attention. If you're unsure, back it out and start again. No real issues with build quality; it feels solid. I didn't notice any give in the attachments.The bad: the instructions are a total waste of your time and aren't worth the paper on which they're printed. You might as well throw them in the bin with the shrink wrap. The way this tool works is this: pull out the end cap and twist it freely while you look at the gauge. The more you turn, the further the gauge goes. One full revolution increases the torque by 2nm, so successive turns take you to 3, 5, 7, 9nm, and so-on. To get values in between, you can stop the handle at the appropriate spot midway between turns; the torque is the sum of the lower gauge value and the handle position, so if you want 3.4, you'd wind down to 3 on the gauge, then turn the handle up to 0.4. The positions are marked every 0.4nm, but there's an actual stop every 0.2nm. It's a little confusing because if you want 4nm, and you look at the gauge and the handle, it looks like your only options would be 4.2 or 3.8nm; however, there is an unmarked stop between the 0.8 and 1.2 handle positions that adds 1 to the gauge value.And now you know everything you need to know about how to operate this wrench, none of which is clearly explained on the instruction sheet, which, again, belongs in your trash bin.So 5 stars for a good wrench, minus one star for a terrible instruction sheet.
